Xaar and Lawter Collaborate on Nanosilver

Xaar plc, which makes industrial inkjet technology, and Lawter, along with its parent company Harima Chemicals Group (HCG), are now collaborating to optimize the performance of a line of nanosilver conductive inks in the Xaar 1002 industrial inkjet print-head.

The combined solution, according to the companies, will be of interest to manufacturers of consumer electronics goods looking for a method to print antennas and sensors with silver nanoparticle ink as part of their manufacturing processes.

Xaar explains inkjet is a cleaner process than other methods of printing silver inks; this is especially relevant when printing onto a substrate, such as a display, in which any yield loss is expensive. With inkjet, manufacturers can precisely control the amount of ink dispensed in certain areas of a pattern, continues Xaar, so that the ink or fluid deposited can be thicker in some areas and thinner in others – adding that inkjet enables the deposition of a much thinner layer of fluids than traditional methods, which is significant for the manufacturers looking to produce thinner devices. Inkjet is also one of the few technologies able to print a circuit over a substrate that has a structured surface.

“This is an excellent opportunity to showcase our latest technological breakthroughs and demonstrate the unique value that our revolutionary nanoparticle inkjet solutions can play as part of an integrated system solutions in the PE world,” said Dr. Arturo Horta, Business Development Manager for Lawter Innovation Group.

HCG claims to have pioneered the development and manufacture of silver nanoparticle conductive inks for the printed electronics industry over 20 years ago and has over 100 patents related to its nanoparticle dispersion technology.
